domain of f(x)=x^2+y^2+2x+4y+4=0

domain

f (x) = x^{2} + y^{2} + 2 x + 4 y + 4 = 0

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < x < \infty

y = lo g_{10} (8 - 4 x)

f (x) = - (x - 6)^{2} - 26

ln (t^{2} - 1)

f (x) = lo g_{3} (x + 2) - 2

f (x) = \frac{3 x + 9}{5}

What is the domain of f(x)=x^2+y^2+2x+4y+4=0 ?
The domain of f(x)=x^2+y^2+2x+4y+4=0 is -infinity <x<infinity
